Here is my Html:
<iframe onload="reloadOnce(this)" frameborder="no" src="cloud.php" class="foo1" scrolling="no" seamless="seamless" allowTransparency="true" width="100%" height="90em"></iframe>
and Here is my CSS
.foo1{margin: 0; padding: 0; width:100%; height:90em; overflow-x: scroll; }
As I know, overflow-x: scroll; is not necessary, even I removed it, but still It's same. I'm using this for parallax web scrolling. For your information, I tried to use z-index: function, but not effected!
Actually mouse scrolling is working in other web areas but not in iFrame specific area.
Thanks in Advance.
